Postgres connection string with schema, alembic sqlalchemy - postgresql

Question

I am working on Alembic with SQLAlchemy on my Alembic.ini I am setting my postgres connection string but it goes to my public schema, i need to choose my schema.
How I can use an specific schema:
alembic.ini file
sqlalchemy.url = postgresql://myuser:mypassword#server:host/database
models.py
import datetime
from sqlalchemy import Column,Integer,String,DateTime,create_engine
from sqlalchemy.orm import declarative_base,sessionmaker
Base = declarative_base()
class UserModel(Base):
__tablename__='myschema.person'
id = Column(Integer, primary_key=True)
first_name = Column(String, nullable=False)
last_name = Column(String, nullable = False)
birth = Column(DateTime)
This connection string works with public, I need to connect to my "sales" schema.
On my models.py I am just creating a table person, I tried adding there Core schema but didn't works

Here you can find a complete working example
Define schema on your model
class A(Base):
__tablename__ = 'a'
__table_args__ = {
"schema": "alphabet"
}
edit env.py to work with schemas
with connectable.connect() as connection:
"""
Configure migration context
1. Pass our models metadata
2. Set schema for alembic_version table
3. Load all available schemas
"""
context.configure(
connection=connection,
target_metadata=target_metadata,
"""
here you are passing schema
"""
version_table_schema=target_metadata.schema,
include_schemas=True
)
Run alembic revision and upgrade and it will work
